8.0 - MAINTENANCE
Maintenance and replacement work must be done by expert maintenance technicians trained
in the observance of applicable laws on health and safety at work and the special ambient
problems attendant on the installation.
Before doing any work on the unit, the operator must first switch off power to the gear unit
and ensure that it is out of service, as well as taking all necessary precautions against it be-
ing accidentally switched on again or its parts moving without warning (due to suspended lo-
ads or similar external factors).
Furthermore, all additional environmental safety precautions must be taken (e.g. elimination
of residual gas or dust, etc.)
.
•
Before doing any maintenance work, activate all safety equipment and, if necessary, inform persons wor-
king in the vicinity. In particular, mark off the area around the unit and prevent access to any equipment
which, if activated, might be the cause of unexpected health and safety hazards.
•
Replace worn components with original spare parts only.
•
Use the lubricants (oil and grease) recommended by the Manufacturer.
•
When working on the gear unit always replace gaskets and seals with new original ones.
•
If a bearing requires replacement, it is good practice to also replace the other bearing supporting the same
shaft.
•
We recommend replacing the lubricating oil after all maintenance work.
The above instructions are aimed at ensuring efficient and safe operation of the gear unit.
The Manufacturer declines all liability for injury and damage to components due to the use of non-original spa-
re parts and non-routine work which modifies the safety requirements without the express prior authorisation of
the Manufacturer.
Refer to the specific spare parts catalogue when ordering spare parts for the gear unit.
Do not dump polluting liquids, worn parts and maintenance waste into the environment. Di-
spose of all such materials as stipulated by applicable legislation.
•
Observe the routine inspection and maintenance schedule to ensure suitable operating condi-
tions and the effective explosion protection of the unit.
•
Always apply fresh Loctite 510 paste or equivalent product with similar properties and applica-
tion range to all disassembled threads.
•
Before servicing or repairing internal components, allow the gear unit to cool down completely
before opening the casing so as to avoid burns from parts which are still hot.
•
Make sure, on completion of maintenance work, that all safety measures and equipment have
been applied and reset.
•
Clean the gear unit thoroughly after maintenance work and repairs.
•
On completion of maintenance work, tighten all vent, filler and level plugs to their specified tor-
que (table A0).
•
On completion of any maintenance work, all seals must be refitted and sealed as prescribed.
On gear units with double seal rings, the cavity between the two rings must be packed with
synthetic grease (Fluorocarbon gel 880 ITP or equivalent product with similar properties and
application range) before assembly.
•
Regardless of the type of gear unit, whenever a seal ring is replaced its lips should be smea-
red with a thin layer of grease (Fluorocarbon gel 880 ITP or equivalent product with similar pro-
perties and application range) before assembly.
•
Use only original spare parts for repairs.
